Hello,
does someone know if there is any way to lock a texture to an SDL_Surface to
have directly access on texture buffer on AGP memeory ? Otehrwise the only
way is to recreate the texture and rebind it everytime we redraw on it, and
this makes GL copy it on video memory on every changes, but AGP memory CAN
do better than it.
With this, and using an SDL html component you could have 3d html ingame
help floating around you
